# System Requirements

> System Requirements for EXT:ns_t3af (T3AF).

## Purpose

This page lists what your server and TYPO3 instance need before you install **EXT:ns\_t3af**. Check these items on staging before production.

## Core requirements

* **TYPO3 CMS** — 12.4 LTS, 13.4 LTS, or 14.x
* **PHP** — 8.2 or higher (8.3 recommended)
* **Database** — MySQL 8.0+ or MariaDB 10.3+
* **Web server** — Apache or Nginx with HTTPS on production

## Required system extensions

* **workspaces** — Draft workspaces for MCP and safe edits
* **scheduler** — Background AI jobs

## Composer / package dependencies

T3AF is distributed as a T3Planet premium extension package. Do not use a public `composer require` command unless you have access to the required private package source.

**Depends on:**`nitsan/ns-license`, `typo3/cms-workspaces`, `typo3/cms-scheduler`

**Conflicts with:** other MCP server packages (`marekskopal/typo3-mcp-server`, `hn/typo3-mcp-server`, and similar). Remove conflicting packages before install.

## MCP server (optional)

If you plan to use the MCP server:

* **TYPO3** — 13.4+ or 14.3+ for full MCP support
* **HTTPS** — Required for OAuth in production
* **mcp/sdk** — Bundled with T3AF

See [MCP Server](/en/latest/en/latest/ExtNsT3AF/MCPServer/Index).

## Server resources

* **PHP memory** — Minimum 256 MB; 512 MB or more recommended
* **Max execution time** — Minimum 60 seconds; 120 seconds or more recommended for long AI calls
* **Outbound HTTPS** — Required for AI API calls

## External services (at least one)

You need at least one of these before AI features work:

* **AI provider API key** — BYOK (Bring Your Own Key) mode
* **T3Planet Credits** — Managed billing mode (see [T3Planet Credits](/en/latest/en/latest/ExtNsT3AF/T3PlanetCredits/Index))
* **DeepL / Google keys** — Optional, for translation settings in Extension Configuration

## Pre-install checklist

* TYPO3 12.4+ with the supported T3Planet package installation workflow
* PHP 8.2+ with extensions `mbstring`, `json`, `openssl`, `curl`
* HTTPS on production
* Scheduler cron active (every minute)
* API key or credits plan ready
* T3Planet license key for premium install — see [https://docs.t3planet.de/en/latest/License/Index.html](/en/latest/en/latest/License/Index)
